Frequently Asked Questions

Everything you need to know about AI image upscaling

Our AI upscaler uses Real-ESRGAN, a state-of-the-art deep learning model trained on millions of images. It intelligently adds detail and sharpness to low-resolution images, producing results far superior to traditional upscaling methods.

We support JPG, JPEG, PNG, and WebP formats. The maximum file size is 10MB. For best results, use images with at least 256x256 resolution.

2x upscaling doubles your image dimensions (e.g., 500x500 → 1000x1000), while 4x quadruples them (e.g., 500x500 → 2000x2000). 4x produces more dramatic results but takes slightly longer to process.

Absolutely. Your images are processed securely and automatically deleted from our servers after processing. We never store, share, or use your images for training purposes.

Free users can upscale 2 images per day. Upgrade to Pro for unlimited upscales, priority processing, and batch processing capabilities.

Yes! You retain full rights to your upscaled images. Use them for personal projects, social media, print, e-commerce, or any commercial purpose.
